The overall performance of a firewall is crucial in enforcing and administrating security, especially when the network is under attack. The continuous growth of the Internet, coupled with the increasing sophistication of the attacks, is placing stringent demands on firewall performance. This paper describes a traffic-aware optimization framework to improve the operational cost of firewalls. Based on this framework, a set of tools are designed that inspect and analyze both multidimensional firewall rules and traffic logs and construct the optimal equivalent firewall rules based on the observed traffic characteristics. To the best of the knowledge, this work is the first to use traffic characteristics in firewall optimization.
